一种具有加解密功能的智能售电终端设计

摘要

针对电力用户购电难、传统智能售电终端在电力通信过程中数据传输的安全性相对较低等问题,设计了一种具有加解密功能的智能售电终端.该智能售电终端引入国密SMI算法,设计了安全单元,确保了传输数据在通信过程中不被篡改,保障了数据的完整性和机密性,具有很高的实用价值.%This paper has designed an intelligent electricity selling terminal which has encryption and decryption function according to the problems of the power-purchase difficulty to power-user and the security relatively lower of the traditional terminal equipment's transmission data in electrical communieation.This terminal has introduced the SMI algorithm, designed security unit, ensured that the transmission data was not altered in the communication, transmission data' s integrity and confidentiality were not destroyed.lt has great practical value.
